Hi all,

I'm trying to upgrade XWiki from 1.0 to 1.2. The problem comes when I want to import my .xar file (6Mb) and get a Java Heap Space Out Of Memory Exception.

I've checked your admin page http://www.xwiki.org/xwiki/bin/view/FAQ/Howtoincreasethemaximumattachmentsize and it looks like for my problem (file < 10Mb), only MySQL should be changed. So I've changed the max_allowed_packet parameter but the problem still occurs. I don't have anything in Tomcat or MySQL logs, which is a bit strange. The only trace I get is the one bellow. It looks like Lucene breaks because of the file upload not working. Any idea ? How could I get more details in the log ?

There are 2 places where to make changes when you want to import a large XAR:

1) the mysql config as you said,

2) the XWikiPreferences object. Before 1.2 it had a max of 1MB if I recall correctly. In 1.2 we've upgraded it to 30MB I believe. However if you're using your old XWikiPreferences object then you'll have th max_upload_size set to the old value.

See http://jira.xwiki.org/jira/browse/XE-145

Now regarding lucene I don't understand why this the import has anything to do with lucene but there's probably something I don't know here...

Try changing the max file upload parameter in your xwikipreferences and try the upload again.

Thanks,
